[0025] The whole embodiment 1 achieves the effect that people can easily rotate and open the sealing door 6 by operating the hinge 5, facilitate the installation and disassembly work of the internal device, and the observation window 7 arranged on the sealing door 6 can also enable people to intuitively view the running state of the internal electronic components. Once the sealing door 6 is closed, the control console 19 becomes the control core. After the related device is started, the air pump 3 operates immediately, the air in the switch cabinet body 1 is extracted through the air pipe one 2, and is discharged to the outside through the air pipe two 4, and a vacuum environment is gradually formed in the cabinet. After the compressor 14 is started, the nitrogen is sucked through the processor 9 and the air pipe three 8. After the nitrogen enters the processor 9, a series of purification treatments are carried out: the water absorption plate 10 removes water, the activated carbon filter screen 11 adsorbs impurities and harmful gases and sterilizes and deodorizes, and the separation membrane 12 further intercepts unnecessary gases such as oxygen, so as to ensure the purity and insulation performance of the nitrogen. The treated nitrogen is then compressed by the compressor 14.

Such nitrogen not only effectively prevents the generation of electric arc and ensures the safe operation of the equipment, but also significantly reduces the pollution to the environment compared with traditional SF6 and other insulation gases. In the spraying process, the high-pressure nitrogen can also absorb a large amount of heat, effectively reduce the temperature in the switch cabinet, and prevent the damage of high temperature to the electronic components. When the nitrogen reaches the preset concentration in the switch cabinet body 1, the electric one-way valve 17 is automatically closed, and the built-in pressure detector 18 continuously monitors the internal pressure change.
